she now says I have narcissistic personality disorder...
You sound shocked, as if you haven't heard her say insane things before.
One of my wife's enablers asked her if I was a psycopath, or maybe a sociopath. The both looked it up on google. Five minutes later I was both.
My W has also said she expects me to be a total a$$wipe in the divorce making it harder, when we have never, ever discussed divorce. In fact, as this drags out, the disrespect and damage mounting with each passing day, she may be shocked to find I will make it easier...
